abtou w 4 4 provements in "Lamp To all whom it may roncern v M Be it known-that 1. MICHAEL C, REGAN. of the UnitedStates Army. a citizenof the United States. stationed at Fort Mott. in the county of Salem and State of New Jersey. have invented certain new and usefullnr; Attachments for Cells:- and I do hereby declare the following to be a full, clear. and exact-description of the invention. su'ch as will enable others skilled in the art to which it appertainsto make and usethe sa-me.

' The present invention relates to improve-- ments in lamp attachments for cells. and has for an object to provide an improvedattachment whereby miniature or other electric i lamps may be attached to dry or other cells and supported thereon to swing into and out of engagement 'with one terminal or connector for lighting or disconnecting the lamp.

Another object of the present invention resides in providing an improved attachmentof the abovecharacter which will be simple in construction and economical in manufacture. and will he designed for ready attachmentto an of the approved types of cells now in use..

is connected to the negative terminal 3, the samebeing threaded to receivethe binding" nut 7. -1 p -A miniature, or other electric lamp =is shown in Figs. :1 and 2 as being of'the usualconstruction comprisinga bulb 8, a threaded base 9 constituting one terminal, and a head 10 insulatedand projecting from the base"9 and forming the second terminal.

The head 10 on the base 9 is'adapted tooc-" cupy a socket in the upper end of the binding post at when: the lamp is -in-thei' position fll shown in Figs..1'andi2. whereit issupported by the improved lamp holder-and con: nected to the opposite terminal"-3"so as to place the S21111G l11 circuit with the battery- 1, thereby lighting the lamp. 1 v The base 9 of the electric lamp :is adapted to thread orbeotherwise received into a: lamp socket 11. which is formed as disclosed to advantage iniFigs. 1 andzlyby a coaxial series of convolutions bent from one end of a single :wirestrand. From the'upper end of the socket or convolutions 11, the wire strand is. carried. horizontally to provide anarm 12: and at the opposite end of the arm 1'2the wire is wound to provideoneormore coils l3. imparting resiliency to the lamp holder, and from the coils 13 the opposite end of the wire strand isbent vertically, forming a l trunnion 1i. 1

The vertical trunnion ll isfitted to swing in a bearing 15 furnished by a series of cos I axial convolutions bent centrally. from a sec- 5 0nd wire strand. the lower end ofiiwhichis carried horizontally to supply an arm: .16: having its terminal-end flattened andbent circularly. as shown clearlyat 17 in Fig. 3. to embrace the binding post "6.; ayhe reon: it is. secured; by'the nut Fromz-the upper end of they c'onvolutions lfi .the wirestigand is carried horizontally to provide an'arm-1 ;;and vertically to provide a.;l1older l to which maybe'secured a reflector. .Th-is i'eflector. holder may be dispensed with .if desired.

, Attger the attachment is secured to' the c'ell ill be seen that" the lainp.-.which 'iscariied n. the ocket" (11} supported from-the Siing freelifv in a horizontal 15'as a enter. hemsw-ung't'o'the posit-ion shown-*i n'F- gsalaandi ithe term nal head will engage thesocket in the binding post 10 lbyithe action of the .resili'entcoils slight pressnreonthe lampbr arm will also readily yield when encountering.

any obstruction, so as to prevent possible breakage'of the lamp.

Referring now more particularly to Figs.

5, 6 and 7,-the battery, terminals, binding posts and nuts,.are similar to those shown in Figs. 1 and 2, and are similarly numbered, it being understood thateither form of the device may be attached to the same character of cell.

Over the central binding post 1 is secured, by a nut 5, a flat spring 20 bent upwardly, as indicated at 21 and 22, to provide elevated and yielding ends 23 and 21 having sockets 25 and 26 pressed therefrom, and being further bent downwardly at their terminals to provide guides 27 and 28.

The threaded bases 9 of the lamps are received in the sockets 11, wound from a series of convolutions, as described of the lamp holder in connection with the first form of the invention. The sockets 11 are carried on arms 12 formed with coils l3 and trunnions 11, as described and shown in Fig. 4.,

To the opposite terminal 3 is attached a connector, shown more particularly in Fig. 7 to be formed from a single length of wire, or metal of any other equivalentform, bent centrally to provide a yoke 29, which is flattened, as indicated, to receive the pressure of the nut 7 and form good electrical connection. To eitherside of the yoke 29 the wire is bent into arms 30 and 31, and from the outer ends of the arms are bent series of convolu-tions 32 and forming bearings for receiving the trunnions ll of the lamp holders.

The lamp holders are journaled to swing in the bearings 32 and 33 in a horizontal plane, and into and out of engagement with the flat spring 20. Vhen moved into en-- gagement with the Hat spring 20, the terminal heads 10 of the lamp bases 9 will firstencounter the bent-over terminals '27 and 28 of the ends 23 and 21. and will depress such resilient ends to permit the holder and lamp tobe swung farther toengage the heads 10 with the sockets 25 and 26, where the lamps and holders will be yieldingly held in connected position. The lamps are further held in yielding engagement by thecoils 13 of'the holders, and it will be appreciated that should the lamps strike agalnst anyv objectboth the coils 13 and the flat spring 20 will yield and permit the lamp to swing, thereby preventing damage thereto.

It is; tobe understood that while I have .shown and described the members of this improved attachment as being constructed of wire strands, nevertheless the same may be ment may be reversed, the lamp being con-- nected to swing into and out of engagement with the outer terminal 6, and the reflector holding member, or either of the members shown in Figs. 3 and '7, connected to the central terminal 2. The device is also adapted for'connection to other types of cells having dilfercntly arranged terminals than that shown in the drawing, and I do not desire to restrict myself to the forms of the invention shown in the drawings, as obviously changes may/be made in the same without departing from the spirit of the invention, provided such changes fall within the scope of the appended claims.

I claim:

1. The combination with a cell having projecting terminals, of a connector secured in electrical connection with one of said terminals and comprising a single length of wire bent centrally into a series of convolutions to provide a bearing, a lamp holder formed from a single length of wire separate from said connector and including a journal fitted to swing in said bearings, a Series of convolutions arranged to provide a lamp socket, coils bent from said wire holder intermediate the journal and lamp socket. and a lamp removably fitted in said socket and having a projecting terminal adapted to electrically contact with the other terminal of the cell, substantially as described.

2. The combination with a cell having projecting terminals. of a connector bent from a single length of wire having one end coiled about one of the cell terminals, a series of convolutions bent intermediately of said 'wire connector to provide a bearing. an arm bent from the opposite end of said connector and extending from said bearing, a reflector holder carried on said arm and bent from the extremity of said wire connector, a lam holder formed of a single length of wire having one end arranged to provide a journal fitted to swing in said bearing, a series of convolutions bent from the opposite free erd of said wire holder and constituting a lamp socket. a coil bent from said wire holder between said journal and lamp socket. and a lamp fitted in said socket andhaving a projecting terminal adapted to electrically contact with the other cell terminal, substantially as -described. H

3. The combination with a cell having projecting terminals, of a connector consisting of a single length" offwirebent to encircle one cell terminal. a series of convolutions bent from said wire connector to provide a vertically 'disposed bearing, a lamp holder consisting of 'a single length of int Wire bent at one end to provide a journal fitted to swing horizontally in said bearing, a series of coils bent from the opposite'end of said \vire holder to coils bent from said \vire holder intermediate said journal and socket to impart resiliency thereto, a lamp fitted in said socket and having a projecting headed terminal, and a resilient arm disposed in electrical contact with the other cell terminal and having a depression in its free end arranged to be occupied by the headed terminal of said lamp, substantially as described 4c. The combination with a dry cell having terminals projecting from the upper end thereof, a connector formed of a single length of wire bent to engage one of said cell terminals, series of convolutions bent from said Wire connector and providing provide a lamp socket,
